## When to prefer this

Choose this endpoint when you need structured, World Bank WDI-sourced annual economic size and growth time series for Romania (or another country by overriding the code), especially when you want curated indicator selection with source metadata and latest-observation flags, rather than querying the World Bank API directly. Best for agents needing pre-packaged, ready-to-use economic data bundles at low cost per call.

## Known failure modes

- Invalid country code (not a 2-letter ISO code) causes schema validation failure
- Requested year range outside available WDI data returns empty or partial results
- Start year greater than end year may cause an error or empty response
- World Bank WDI source temporarily unavailable leads to upstream data fetch failure
- Payment not processed (x402 protocol failure) results in 402 response with no data
